Tunnel fires have a different dimension comparing to other fires since smoke and temperature disseminate very fast and affect the entire facility. | | While one of the vehicles underway in the tunnel may have an accident and cause pileup, and it carries a large fire load for such fires which may occur after the accident. | | We design the tunnel fire concept with out specialist employee within the structure of our company who has doctorated on “tunnel fires”, and we furnish services of project, application and/or consultancy. | | Automatic tunnel fire extinguishing systems should be preferred than manual ones. Let’s consider the reasons depending on the lessons taken from the tunnel fires which have occurred up to now; |
| • | Fire spreads fast, there is the lack of trained persons to operate manual systems. | | • | Persons remained in the tunnel prefer to escape and do not participate in the fire defense due to intense smoke and life safety. | | • | Existing manual systems will be used only by fire brigade teams to arrive to the scene of accident. And this means loss of time. |
| Maintenance, periodical inspections and tests are made in accordance with the principles and periods in the document “NFPA Test and Maintenance, Inspection“. |
